This paper presents a new solar-assisted heat pump technology for domestic houses based on endothermic panels that integrate within the fabric of the building to provide effective space heating and cooling. The main components in the system are described and the setting up of the demonstration system built at Thermal Sciences Laboratory of the second Engineering Faculty of the Technical University of Bari in Taranto is presented. Initial operational results from the system are presented to show that the technology is effective in collecting and dissipating large quantities of energy so that high coefficients of performances are achieved.
